don't know how unique this is, as hard drive sizes make it less relevant, but I have gotten pretty used to downloading files to RAM, and then unpacking them to a location on the hard drive.
Ditto for cache files for web browsing. (which has the advantage of speeding up the old girl on the web too)
In the windows/mac world,the idea of screens would be pretty unique, particularly swapping back and forth effortlessly. In linux, this is covered of course.
